We report an extended whole-mount in situ hybridization procedure for Drosophila embryos. By using probes labelled with digoxigenin, fluorescein and biotin, respectively, this protocol allows the detection in three colours of RNAs derived from three different genes. Hybridized probes are detected by consecutive staining with appropriate alkaline phosphatase conjugates using different chromogenic substrate combinations, and serial removal of the antibody conjugates by low pH washes.
我们报道了一种用于果蝇胚胎的扩展的全胚胎原位杂交程序。通过分别使用标记有地高辛、荧光素和生物素的探针,该方案允许在三种颜色中检测来自三种不同基因的 RNA。通过使用不同显色底物组合的适当碱性磷酸酶缀合物连续染色来检测杂交探针,并通过低 pH 洗涤来连续去除抗体缀合物。
